jQuery override default validation error message d

Question

I'm trying to over ride the default error message label with a div instead of a label. I have looked at this post as well and get how to do it but my limitations with CSS are haunting me. How can I display this like some of these examples:

Example #1 (Dojo) - Must type invalid input to see error display
Example #2

Here is some example code that overrides the error label to a div element

$(document).ready(function(){
            $("#myForm").validate({
                rules: {
                    "elem.1": {
                        required: true,
                        digits: true
                    },
                    "elem.2": {
                        required: true
                    }
                },
                errorElement: "div"
            });                  
        });

Now I'm at a loss on the css part but here it is:

div.error {
        position:absolute;
        margin-top:-21px;
     margin-left:150px;
     border:2px solid #C0C097;
        background-color:#fff;
        color:white;
        padding:3px;
        text-align:left;
        z-index:1;
        color:#333333;
     font:100% arial,helvetica,clean,sans-serif;
     font-size:15px;
     font-weight:bold;  
    }

UPDATE:

Okay I'm using this code now but the image and the placement on the popup is larger than the border, can this be adjusted to be dynamic is height?

if (element.attr('type') == 'radio' || element.attr('type') == 'checkbox') {
   element = element.parent();

   offset = element.offset();
   error.insertBefore(element)
   error.addClass('message');  // add a class to the wrapper
   error.css('position', 'absolute');
   error.css('left', offset.left + element.outerWidth());
   error.css('top', offset.top - (element.height() / 2)); // Not working for Radio, displays towards the bottom of the element. also need to test with checkbox
} else {
   // Error placement for single elements
   offset = element.offset();
   error.insertBefore(element)
   error.addClass('message');  // add a class to the wrapper
   error.css('position', 'absolute');
   error.css('left', offset.left + element.outerWidth());
   error.css('top', offset.top - (element.height() / 2));
}

the css is the same as below (your css code)

Html

<span>
<input type="radio" class="checkbox" value="P" id="radio_P" name="radio_group_name"/>
<label for="radio_P">P</label>
<input type="radio" class="checkbox" value="S" id="radio_S" name="radio_group_name"/>
<label for="radio_S">S</label>
</span>

Answer 1

Unfortunately I can't comment with my newbie reputation, but I have a solution for the issue of the screen going blank, or at least this is what worked for me. Instead of setting the wrapper class inside of the errorPlacement function, set it immediately when you're setting the wrapper type.

$('#myForm').validate({
    errorElement: "div",
    wrapper: "div class=\"message\"",
    errorPlacement: function(error, element) {
        offset = element.offset();
        error.insertBefore(element);
        //error.addClass('message');  // add a class to the wrapper
        error.css('position', 'absolute');
        error.css('left', offset.left + element.outerWidth() + 5);
        error.css('top', offset.top - 3);
    }

});

I'm assuming doing it this way allows the validator to know which div elements to remove, instead of all of them. Worked for me but I'm not entirely sure why, so if someone could elaborate that might help others out a ton.

If you could provide some reason as to why you need to replace the label with a div, that would certainly help...

Also, could you paste a sample that'd be helpful ( http://dpaste.com/ or http://pastebin.com/)

You can use the errorPlacement option to override the error message display with little css. Because css on its own will not be enough to produce the effect you need.

$(document).ready(function(){
    $("#myForm").validate({
        rules: {
            "elem.1": {
                required: true,
                digits: true
            },
            "elem.2": {
                required: true
            }
        },
        errorElement: "div",
        wrapper: "div",  // a wrapper around the error message
        errorPlacement: function(error, element) {
            offset = element.offset();
            error.insertBefore(element)
            error.addClass('message');  // add a class to the wrapper
            error.css('position', 'absolute');
            error.css('left', offset.left + element.outerWidth());
            error.css('top', offset.top);
        }

    });
});

You can play with the left and top css attributes to show the error message on top, left, right or bottom of the element. For example to show the error on the top:

    errorPlacement: function(error, element) {
        element.before(error);
        offset = element.offset();
        error.css('left', offset.left);
        error.css('top', offset.top - element.outerHeight());
    }

And so on. You can refer to jQuery documentation about css for more options.

Here is the css I used. The result looks exactly like the one you want. With as little CSS as possible:

div.message{
    background: transparent url(msg_arrow.gif) no-repeat scroll left center;
    padding-left: 7px;
}

div.error{
    background-color:#F3E6E6;
    border-color: #924949;
    border-style: solid solid solid none;
    border-width: 2px;
    padding: 5px;
}

And here is the background image you need:

_{(source: scriptiny.com)}

If you want the error message to be displayed after a group of options or fields. Then group all those elements inside one container a 'div' or a 'fieldset'. Add a special class to all of them 'group' for example. And add the following to the begining of the errorPlacement function:

errorPlacement: function(error, element) {
    if (element.hasClass('group')){
        element = element.parent();
    }
    ...// continue as previously explained

If you only want to handle specific cases you can use attr instead:

if (element.attr('type') == 'radio'){
    element = element.parent();
}

That should be enough for the error message to be displayed next to the parent element.

You may need to change the width of the parent element to be less than 100%.

I've tried your code and it is working perfectly fine for me. Here is a preview:

I just made a very small adjustment to the message padding to make it fit in the line:

div.error {
    padding: 2px 5px;
}

You can change those numbers to increase/decrease the padding on top/bottom or left/right. You can also add a height and width to the error message. If you are still having issues, try to replace the span with a div

<div class="group">
<input type="radio" class="checkbox" value="P" id="radio_P" name="radio_group_name"/>
<label for="radio_P">P</label>
<input type="radio" class="checkbox" value="S" id="radio_S" name="radio_group_name"/>
<label for="radio_S">S</label>
</div>

And then give the container a width (this is very important)

div.group {
    width: 50px; /* or any other value */
}

About the blank page. As I said I tried your code and it is working for me. It might be something else in your code that is causing the issue.

Add following css to your .validate method to change the css or functionality

 errorElement: "div",
    wrapper: "div",
    errorPlacement: function(error, element) {
        offset = element.offset();
        error.insertAfter(element)
        error.css('color','red');
    }

Answer 5

I use jQuery BeautyTips to achieve the little bubble effect you are talking about. I don't use the Validation plugin so I can't really help much there, but it is very easy to style and show the BeautyTips. You should look into it. It's not as simple as just CSS rules, I'm afraid, as you need to use the canvas element and include an extra javascript file for IE to play nice with it.

That answer really helped me, in my case i had to filter some elements out and have special aligment on their error div,

errorPlacement:function(error,element) {
    if (element.attr("id") == "special_element") {
        // special align
    } else { // default error scheme
        error.insertAfter(element);
    }
}
